Figure'll is a front view of the plate illustrated in Figure 10.

Figure 12 illustrates the blade holding member for the single edge blade.

In the drz'nvings my stropper A is formed in a manner to provide a very compact case B which is formed wit-h an upper case member 10 and a lower case member 11 which are hingedly connected together at 12.

The case B of my stropper A is designed to provide means for receiving a razor blade, either of the double or single edge type, and the stropper is designed to hold the razor blade when not desired for use within the stropper case B. The stropping strap C is connected to the case by passing through the slot 13 in the flange 1% formed on the free end of the cover member 10 and beneath the trans verse rib member 15 extending across the top portion 10 adjacent the flange 1 1. This rib member is provided to hold the stropping strap in close proximity to the blade within the stropping case B. The strap then extends about the tubular member 16 which is positioned on the pin 1'? and holds the case members 10 and 11 pivotally' connected together at 12. The strap then extends from the member 16 along the inside of the bottom case member 11 and over the rib 18 and out through the slot 19 formed in the upwardly PlO'JGCtlIlg flange 20 formed on the tree end of the bottom member 11 of the case B. hen the case B is in closed position the flanges l and 20 meet so as to form a closure along the free end of the case members and throughwhich the strap C passes. y

The strap C is termed with suitable engaging handles 22 on either end which are adapted to be engaged to draw the strap back and forth through the case B. a

A pair or side arms 25 are pivotalhx sup ported through the opening 26 to atta -h the same at the pivot point 12 on one end, while the other end formed with an offset end portion 27 :trom which the portion 28 extends approximately at right angles to the portion 2?, and from the port-ion 28 the portion 29 is bent to extend approximately at right angles to the port-ion 28. Thus the portions 27 and 29 are extended approximately parallel to each other, thereby providing an offset supporting bracket arm on the free end of the arm 25.

There are two arms 25 in my strop A, one being positioned on each side of the case B, as illustrated in Figure 1 of the drawings and in Figure 8. The portion 29 is adapted to extend through the slots 30 formed in the cover 10 of the case B and by means of the lug 31 the portion 29 engages beneatlrtlie inside of the cover 10, as illustrated in Figure 4. Thus the lugs 31 form an engagement with the inside of. the cover 10 to hold the free end of the arm 25 firmly connected to the free end of the cover 10. Adjacent "the lugs 31 E provide short lugs 32 which are adapted to support one end of the coil 'springsg fi. The other end of the coil springs 33 engage over the lugs 3% formed on the depending flange 1st vof th cover 10, as clearly illustrated in Figure 9 and also illustrated in Figure 4.

The cover 10 isformed with depending ears 35 on either side or the same in which 1 provide slots 2:36 which are adapted to engage over the pin 12 to pivotally and slid-ably support "1' 10 atjthe pivot point or rod 12. At the back of the cover an arcuated skirt 3? is provided to close the back of the case B and to provide a neat and smooth construction to the stroppercase. Gn the free end or" the cover 10 Iprovide projecting shoulders 38oueither sideot the same which are adapted to engage beneath the hooks 39 in a manner to attach the cover 10 to'the bottomll. The hooks 39 are formed on the upwardly projecting side walls of the cover 11. r

In opening and closing the case of my stropper A it is only necessaryto engage that portion of the strap C'which extends through the bottom 11 and through the flange 20 out through the slot 19, and pull the same sufiiciently to cause the attaching portion of the handle 22 to strike against the flange 1 1 of the cover 10, which causes the springs to be compressed, and by means of the slots SG'the cover 10 is adapted to slide backward sutiiciently to release the lugs or shoulders 38 from the hooks 39, whereupon the cover it) automatically opens by reason of the pull strap. In this manner I provide a stropper case B which automatically opens by pulling on one end of the strap U.

The case B adapted to conceal the razor blade l) which is illustrated in dotted outline in Figure 6, so that when the stropper A in use, the razor blade is entirely concealed and protectejlwithin the case B. Iprovide razor. blade supporting arms iltlfwhich are rigidl: ecured to the ends of the sleeve 16 and winch are formed with arcuatcd lugs ii on one end of the same, while the free end -12 is formed with a bifur *ated end to provide lugs 43 adapted to receive the razor blade supporting plate The razor blade supporting plate at; is adapted to tit freely between the lugs 43 so that it 'canoscillate back and 'forth between the lugs 43 freely in operation. The razorblade supporting plat'el45 is formed with a pair of short lugs46 extend ing from each side of the same which are adapted tobe engaged by the ends of the springs 47 carried bythe pivot member 12. The springs 47 are provided with arms 48 and 49, the arm, 49 being formed witha hook end 50 which extends over theend 51 of the arm 48. The arm 48 extends on one side of the lugs 46, while the arm 49 extends on the other side, and thelugs 46 areiormed with an upwardly bent end which extends at right angles to the plate 45 softhat. the spring arms 48 and49 are held in amannerto engage on either side of the plate 45 and to prevent disengagement of the free ends, of the spring 47 from the plate 45.; The springs 45 tunetion to hold the plate 45 normally parallel with the sides otthe case 1 and 11; These .springs47 are very sensitivein action and tend to movethe razor la-de supporting plate 45 parallel with the sides of the strap C as quick as pressure or pull is released from I the ends of the strap, thus preventing cutting of the strap instropping. i The plate t is formed with apair of long lugs 52 which areadapted to extendbeyond the lugs '46 and engage in the slots 53;-i-nthe side walls ofthe bottom 11 whenth'e case B' The clam )in )late 56. is of a sim ale Iflatnal e l l 7 ture and is freely disposedin the openings .57 so that it-will pivot readily to adjust itself with the blade carrying plate 45. lVhen the cover is closed, the plate 56 bears down against the plate 45 in a manner to clamp the razor blade betweenthe two plates.

In stropping the blade F," the blade is placed on the plate 45 when the same is. held in the elevated position illustrated in- Figure 4. The lugstl function to cause the opening of the case B toraise the plate 45 by causing the arms to be centered between the sides 1.0 and 11 of the case B. This holds the plate elevated when the case is open and permits the blade to be easily engaged toremove it or to fit the samelon theplate; \Vhen' the case is closed the plate 56 engagesand clamps theblade to the plate 45, y p

In stropping, the ends 22 of the stropper are engaged and by means oftheholding loop 60 which is formed with hookends 61 tofree ly pivot the loop 60 to a pair of ears 62 which are riveted to the endofthe pivot rod 12 so that the ears 61will pivot freely at the the member 16 causingfriction to move the arms 40toward either side of the'strap C. As t-hearms40move toward the strap in the direction of the pull, the razor supporting pivot point orrod 12, the strap 0 can be pulled back and forth by engaging in-the hand loops 22, andcause the strap C to slide over plate 45 is adaptedto adjust itself in a manner to permit the cutting edges of the blade E to bear against the strap and thus automatically strop the blade, the springs 47 moving the blade to neutral position the moment that the stropping ceases. As theends of the strapC are pulled back and forth the blade E'is'reoiprooated fromone side to the other to str'op the cutting edges onboth sides. In this form ofblade as illustrated by the dotted outline .asthe razor bladeE,'the double cutting edge is provided and the plate-45 together with the clamping plate 56 will permit therazor blade to movebackeand forth to freely stron the cutting edges. I

hen thestropping operation complete,

it is only necessary to pull on one ofthe han- (lle's 22 and release the other end ofthe strap p C so that it will pull against tliezt'ree end of I I the cover '10. Thereupon thecase B automaticallyopens and the razor blade-E is elevat'ed automatically into the position of the arm 40 in Figure 4. The operationof my stropper his very simple, yet it is effective,

and the'neat compact construction very desirable for a stropperof this nature. The

holding loop GOcan be foldedover onto the case as illustrated in Figure 5, and the ends of the strap C can be foldedaboutthecase B,,thus forming a very compact stropp er A, I with the razorblade E held and protected within thesame and permittingthe stropper tobe packed into a very compact state when not beingnsed. Nevertheless, the strop'is ready for use at any timeand by engaging the holdlng loop60 over ahook on thewall,

the; ends 22 canbe engaged and in a few moments the razorblade E stroppedft-hon ou lil and the stropper A automatically opened by pullingon one of the handles.

' By meansof the blade receiving plate 65 illustrated inFigu'res 10 and 11,. a razor blade with a singlecutting'edge, such as is illustrated in dotted outline in Figure 10, can be stropped readily in my stropper A. The razor blade F in this holdingmeans is held on the plate 65 sliding beneath the ears 66 andbeing clamped by thev clamping bar 67. he. clamping bar. 67is supported at the pivot point 57 in the a-rms25, while theplate 65 is supported by the arms 40. This blade holding means in Figures 10, 11 and 12, functions just the same as that heretofore described, excepting that it is. adapted, to hold a singlefedge blade. Therefore, it is readily apparent that my stroppe-r A is adapted for different razor-blades..- y I e It is an essential feature of my invention, however, to provide a razor stropper ofsimplicity, compactness and of an automatic nature, so that the cover snaps into locking position automatically, and also opens automatically by pulling on one end of the strap, and the blade is adapted to be self-centering automatically by the spring means provided to hold the same against cutting the strap. The feature of elevating the blade is also of importance as it permits the blade to be readily engaged or placed within the stropper A.

In aecordancewith the patent statutes I have describedthe principles of operation of my razor strop A and while I haveillustrated a particular formation and construction of the same, I desire to have it "understood that the same is only illustrative and that other forms of my invention ca be adapted for the purposes set forth within the scope of the following claims.
